Walter SF-5 Non-Ferrous Carbide Burr 1/2-Inch

Stop Clogging Your Burrs on Aluminum

Every welder knows the frustration of grinding aluminum with the wrong burr. The soft metal gums up the flutes, the tool overheats, and you spend more time cleaning the bit than actually working. The Walter 01W316 Allsteel Carbide Burr SF-5 NF is the solution. Engineered with a specialized Non-Ferrous cut, this burr is built to chew through aluminum, magnesium, and other soft metals without loading up. The wide, open flute design throws chips clear of the cutting head, keeping the tool cool and the cutting action aggressive.

This model features the popular SF-5 shape (Tree with Radius End), which is a favorite among fabricators for its versatility. The pointed nose allows for precise work in tight corners, while the radiused body is perfect for blending welds and smoothing out contoured surfaces. With a 1/2-inch head diameter and a 1-inch length of cut, it offers a substantial working surface for efficient material removal. The standard 1/4-inch shank fits universally in almost all air and electric die grinders found in welding shops.

Walter Surface Technologies manufactures these burrs in the USA to strict tolerances. This means you get a perfectly balanced tool that runs true. A balanced burr reduces chatter and vibration, which gives you better control over the grind and leaves a cleaner finish. It also saves your hands from the numbness caused by vibrating tools. If you work with aluminum fabrication, trailer repair, or custom alloy work, the Walter 01W316 is an essential addition to your tool arsenal.

Why Choose the SF-5 NF?

• No Loading: Specifically designed flutes keep aluminum from sticking.
• Versatile Shape: Tree shape handles both flat blending and tight radius work.
• Smooth Operation: Precision shank reduces vibration and chatter.
• Long Life: Premium carbide stays sharp longer than standard high-speed steel.
